Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

answer is c
how 1 unit change in b causes a 50 unit change in x? I am unable to see what you could see, please make it more explicit.
since x=50b-99, here b is a multiple of 50, so 1 unit change in b cause a 50 unit change in x. for example let b=1 then x=-49 now i change 1 unit in b and take b=2 then x=1 here change in x from-49 to 1 is 50 units
